In Chap. 5, p was defined as the fraction (or probability) of functional groups that had reacted at a certain point in the polymerization. According to the current definition provided by Eq. (6.66), p is the fraction (or probability) of propagation steps among the combined total of propagation and termination steps. The quantity 1 - p is therefore the fraction (or... 

The Textile Eiber Product Identification Act (TEPIA) requires that the fiber content of textile articles be labeled (16). The Eederal Trade Commission estabhshed and periodically refines the generic fiber definitions. The current definition for a polyester fiber is "A manufactured fiber ia which the fiber-forming substance is any long-chain synthetic polymer composed of at least 85% by weight of an ester of a substituted aromatic carboxyUc acid, including but not restricted to terephthalate units, and para substituted hydroxyben2oate units."... 

In the United States, chocolate and cocoa are standardized by the U.S. Food and Dmg Administration under the Federal Food, Dmg, and Cosmetic Act. The current definitions and standards resulted from prolonged discussions between the U.S. chocolate industry and the Food and Dmg Administration (FDA). The definitions and standards originally pubUshed in the of December 6, 1944, have been revised only slightly. 

Eirst of all, what is meant by a solid surface Ideally the surface should be defined as the plane at which the solid terminates, that is, the last atom layer before the adjacent phase (vacuum, vapor, liquid, or another solid) begins. Unfortunately such a definition is impractical because the effect of termination extends into the solid beyond the outermost atom layer. Indeed, the current definition is based on that knowledge, and the surface is thus regarded as consisting of that number of atom layers over which the effect of termination of the solid decays until bulk properties are reached. In practice, this decay distance is of the order of 5-20 nm. 

Finally, in this Introduction, it is worthwhile to reproduce one of the several current definitions, in the Oxford English Dictionary, of the word simulate To imitate the conditions or behaviour of (a situation or process) by means of a model, especially for the purpose of study or training specifically, to produce a computer model of (a process) . The Dictionary quotes this early (1958) passage from a text on high-speed data processing A computer can simulate a warehouse, a factory, an oil refinery, or a river system, and if due regard is paid to detail the imitation can be very exact . Clearly, in 1958 the scientific uses of computer simulation were not yet thought worthy of mention, or perhaps the authors did not know about them.

As you will learn in this chapter, the modern definitions for oxidation and reduction are much broader. The current definitions are based on the idea of electron transfers, and can now be applied to numerous chemical reactions. In Unit 1, you saw the terms oxidation and reduction used to describe changes to carbon-hydrogen and carbon-oxygen bonds within organic compounds. These changes involve electron transfers, so the broader definitions that you will learn in this chapter still apply. 

Describe in detail the current definition of a planet. How does it differ from the definitions of stars and asteroids If size becomes a defining characteristic of a planet, hem will that change the solar system as we know it today ... 

Apart from changing the definition of a medicinal product, the definition of risks related to use of the medicinal product has also been changed. The definition now has four components - in addition to the current definition which defines risk to public health in terms of the quality, safety and efficacy of the product, the revised legislation requires an assessment of any undesirable effects on the environment from use of the product. 

Note 2 The earlier term polycondensation was synon5nnous with condensation polymerization. It should be noted that the current definitions of polycondensation and eondensative chain polymerization were both embraced by the earlier term polycondensation. 

Despite these impressive results, it is important to note several limitations of this study retrospective design, application of additional therapies after ECT, and lack of ECT measurements and of currently definitive objective instruments in the measurement of OCD and depression. In our opinion, ECT does not have antiobsessive properties, and our experience is in contradiction with that of Maletzky et al. (1994). 

A current definition of "explosifs de surete" is given in the French "Reglement pour le Transport des Matieres Dangereuses as follows An "expiosif de sfiret " is an explosive which does not present any danger of explosion in mass either by combustion or by shocks (impacts) of the highest intensity which may be produced in the course of transportation and handling (See Ref 6, p 213, footnote)... 

Measurement uncertainty characterizes the extent to which the unknown value of the measurand is known after measurement, taking account of the information given by the measurement. Compared with earlier, more complicated definitions, the current definition of measurement uncertainty is quite simple, although it does not give much guidance on how it is to be estimated. What information should be used, and how should one use it ... 

Another aspect of delocalization, the mixing of Kekule structures and the energetic gain associated with it, will also be quantitatively investigated, and finally our results will be placed into the context of the thermochemical properties of hydrocarbons and the current definitions of resonance energy.

The system for classification and disposal of hazardous chemical waste developed by EPA under RCRA does not apply to all wastes that contain hazardous chemicals. For example, wastes that contain dioxins, polychlorinated biphenyls (PCBs), or asbestos are regulated under the Toxic Substances Control Act (TSCA). In addition, the current definition of hazardous waste in 40 CFR Part 261 specifically excludes many wastes that contain hazardous chemicals from regulation under RCRA, including certain wastes produced by extraction, beneficiation, and processing of various ores and minerals or exploration, development, and use of energy resources. Thus, the waste classification system is not comprehensive, because many potentially important wastes that contain hazardous chemicals are excluded, and it is not based primarily on considerations of risks posed by wastes, because the exclusions are based on the source of the waste rather than the potential risk. 

EPA s current definition of high-level waste was first developed in 1985 (EPA, 1985) and is contained in 40 CFR Part 191 (EPA, 1993a). This definition defers to NWPA, and spent fuel is defined separately from high-level waste as in the Act. Thus, EPA has adopted the traditional, source-based definition of high-level waste.
